Abstract: Provided is a display device. The display device includes a display panel including a common voltage generator generating an output voltage to be provided to the plurality of pixels. Each of the plurality of pixels includes a pixel electrode receiving a data voltage, a common electrode receiving the output voltage through common voltage lines, and a liquid crystal capacitor charged with a voltage difference between the data voltage and the output voltage. The common voltage generator compensates the output voltage based on a ratio of an internal resistance of the common voltage generator to a resistance component of the common electrode disposed on the display panel and outputs the compensated output voltage.

Abstract: A display device includes a first gain provider which controls a first gain value during a first display period in which a still image is displayed, a second gain provider which controls a second gain value during a second display period in which a moving image including a still area is displayed, and a grayscale converter which applies the first gain value or the second gain value to an input image and generates an output image. The first gain provider linearly or exponentially increases the first gain value to a maximum gain value based on a load of the still image from a first time point when the second display period changes to the first display period to a second time point at which the first gain value starts to decrease from the maximum gain value.
